To all whom it may concern:

Be it known that I, ARTHUR CAMERON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Safety-Razors, of wliiph the following is a specification.

3 safety type, and has for its object, first,

to avoid punching one or more holes in the blade, as in the case of certain safety razor blades requiring such holes for the reception of studs or the like for the purpose of holding the blade against lateral shift, it being understood that in order to provide a high carbon blade with such holes it must be annealed and thereby involve undesirable expense; second, to securely hold in place either a single or double edged blade Without causing or permitting the cutting edge or edges to abut or contact with any shoulder or shoulders or stop or stops; third, to accurately define the position of said blade, and to steadily and securely hold it in place in a simple and efl'ective way; to further provide for easy cleaning of the blade and holder therefor; and to provide a simple economical and generally desirable construction of safety razor.

In the accompanying drawing: Figure 1 is a perspective view of a safety razor embodying my invention. Fig. 2 is a perspective view of the clamp plate detached. Fig. 3 shows the blade in perspective. Fig. 4 is a perspective view of the combined comb and frame or plate providing a bed or support for the blade. Fig. 5 is a section taken on a vertical plane transversely through the upper portion of Fig. 1, on a larger scale. Fig. 6 is a plan view of the combined comb and bed or blade holding plate with the blade seated thereon. Fig. 7 is a view of Fig. 6 with the blade removed. Fig. 8 is a section through plate A similar to the section inFig. 5 but at one side of the boss 11 on said plate. Fig. 9 is a detail showing a section on line :0 in Fig. 1. Fig. 10 is a modification showing portions of the blade and comb plate.

A indicates an oblong blade supporting comb plate or frame provided along one of its two longer marginal portions, herein termed its front edges, with a series of guard teeth 1, and having between its ends an opening 2 which is positioned back from the front toothed edge to an extent to leave between the marginal toothed or comb-like invention relates to razors of the from the plane assembled, it being here portion and the said opening 2, a width of plate surface proportional to the width of a blade. This blade supporting plate A, see for example Figs. 4 and 7, has its blade supporting face or surface which is exposed in said figures, preferably flat, and the oblong and relatively narrow blade B-see Figs. 3, 6 and 9, lies fiatwise upon the face portion 3 (Fig. ,7) of such'plate whereby one of its longitudinal edges will lie near the plate opening 2 while its opposite edge portion will extend over the teeth 1 to a suitable extent. These longitudinal edges 4, 4:, of the blade are each sharpened, and therefore to avoid annealing a piece of high carbon steel to permit it to be punctured with holes for securing screws, and also to avoid injury to the blade edges by holdingmeans I provide the blade supporting or holding plate or frame A with end lugs or projections C, forming stops or catches which engage in corresponding or suitable notches or openings 5 with which the blade is provided at its opposite side. The blade thus held against longitudinal and lateral shift on the face of plate A is also held in position whereby its edge portion over the comb or teeth will remain true and also whereby the blade will be firmly held in position without danger of either of its longitudinal cutting edges 4 engaging any part or projectionon the holder. As a simple and convenient way, notches ,5 can be ground in the end of the tempered blade without disturbing the tempered condition of the latter, and where the notches are rounded, the plate A can be made with segmental lugs C projecting up of its face portion 3.

In order to clamp the blade on the plate A in the position shown for exam 1e in Fi% 6, I provide a clamp plate I) a apted to t upon the blade and exposed'face portion 6 of the plate A shown in Fig. 6, this clamp plate D being; provided with end notches 7 in which t e stops or catches C engage when plate D-is fitted upon plate A and the blade B, as in Figs. 1 and 5. The clamp plate is also preferably provided with a flan e 8- extending along one of its longitudina marginal portions, and as shown in Figs. 1 and 5, this flange engages against the untoothed longitudinal edge 9 of the plate A. The clamp plate has its inner side provided with a stem 10 which fits hole 2 of the plate A when the parts are properly observed that plate A is also provided with a boss 11 (Figs. 1 and 5) through which hole 2 is extended, and that the stem which extends through such hole, has a threaded end portion 12 5 which is screwed into a threaded socket 13 in the handle 14, so that by holding the assembled plates and turning the handle, the inner end of the latter Wlll tighten up against the boss 11 and also draw the plates 10 firmly together. As the razor blade B is thin it will be compactly held between the two plates or frames, as evidenced by Fig, 5, and when thus held its longitudinal edges will not become injured. It will also be 15 observed that as the notches 7 in plate it) receive the stops or lugs C, C, the plate D clamps down on the blade when the parts are assembled and tightened up. The lugs C while resisting lateral shift of the blade, also accurately position the latter and thereby define the proper position of whichever longitudinal edge of the blade may be used as the forward cutting edge.

As another way of adapting the blade for engaging plate A, the latter may have raised end portions C provided with lateral recesses C and the blade ends can be ground to form projecting portions 5*, which fit in the recesses C as in Fig. 10.

What I claim as my invention is:

1. In a safety razor, the combination of substantially rectangular supporting guard and clamp plates, said supporting guard plate having comb-teeth on its forward edge and an opening extending through said plate midway between its ends, and said clamp plate having a rigid stem extending through said (opening, a part threaded on said stem and passing through said supporting guard, a threaded member to engage said threaded part of the stem for drawing said plates together, and a reversible, double-edged blade in the form of a narrow imperforate strip having both its edges sharpened and arranged between the forward edges of said plates and entirely in front of said stem, one of said plates having projecting lugs at its ends located midway between said opening in the guard plate and the forward edge of said plate,andthe other of said plates and said blade having end portions formed to interlock with said lugs to position said reversible blade with either. of its edges in operative position,

substantially as described.

2. In a safety razor, the combination of substantially rectangular supporting guard Loeaara and clamp plates, said supporting guard plate having a projecting part midway between its ends with an opening extending therethrough and having comb-teeth on its forward edge, said clamp plate having a flange at its rear edge adapted to overlap the rear edge of said guard plate and also having a stem extending through said open ing, a part threaded upon said stem and passing through said projecting part of the guard plate, a threaded member to engage said threaded part of the stem for drawing said plates together, and a reversible, double-edged blade in the form of a narrow, imperforate strip having both its edges sharpened and arranged between the forward portions of said plates and on the front side only of said stem, one of said plates having projecting lugs at its ends midway between the forward edge of the opening in said supporting plate and the front edge thereof, the other of said plates and said blade having end notches midway between the edges 30 and arranged to interlock with said lugs to position said reversible blade with either of its edges in operative position, substantially as described.

3. In a safety razor, the combination of substantially rectangular supporting guard and clamp plates, said guard plate having a projecting portion midway between its ends with an opening extending therethrough at an acute angle to said plate, said clamp plate having a correspondingly disposed rigid stem arranged to extend through said opening, a part threaded on said stem and passing through the opening in said projecting portiofi, a threaded handle to cngage said threaded part of the stem for drawing said plates together, and a reversible, double-edged blade in the form of a narrow, imperforate strip having both its edges sharpened and arranged between the forward portions of said plates and on the front side only of said stem, one of said plates having projecting lugs at its ends located midway between the opening in the supporting guard and the front edge thereof, and the other of said plates and said blade having end portions formed to interlock the said lugs to position said reversible blade with either of its edges in operative position.
